Tag implication: hand_on_hat->hat

Reason: If someone's hand is on a hat, there's a hat

You may also want to alias/implicate adjusting_hat -> hand_on_hat ; I can't think of a practical way to adjust a hat without using a hand, though that may be lack of imagination. ;p

Somebody else doing the adjusting? (post #715739)

The hand_on_hat tag works for that; it's still a hand on a hat. post #762951, post #810226, post #780724, post #765801 all from the first 3 pages of hand_on_hat
